Abstract
A fluid pressure shock absorber mounted on a vehicle includes: a cylinder tube; a rod inserted into the cylinder tube so as to be movable back and forth; a piston connected to the rod and dividing an interior of the cylinder tube into a bottom-side chamber and a rod-side chamber; a damping valve configured to impart resistance to a flow of working fluid between the bottom-side chamber and the rod-side chamber, the damping valve being capable of changing damping characteristic in response to a pilot pressure; and a solenoid valve configured to switch supply and shut off of a pilot pressure to the damping valve, wherein the working fluid in the bottom-side chamber or the rod-side chamber is used as the pilot pressure.
